The graph shows the information of production levels of the main kind of fuel in the UK between 1981 and 2000.
Overall, it is clear that petroleum production levels was significantly higher than coal and natural gas for the entire period.
In 1981, the UK produced 90 tonnes of petroleum, then increased significantly to 140 tonnes in 1984 before remaining stable over the next 7 years. By 1991, this figure dropped to the lowest point, recording at only 100 tonnes before experiencing a strong recovery at the end of the period. Meanwhile, natural gas tended to rise much more steadily than natural gas surpassed coal production levels in 1991 at approximately 92 tonnes and finished at 120 tonnes.
By contrast, the UK produced less and less coal power over 20 years, starting at 80 tonnes. Coal production dropped dramatically to under 40 tonnes in 1984 before returning to 60 tonnes in 1986. Coal production levels gradually decrease over the remaining years ending of the period with 37 tonnes.
